4.2 Inch Corrugated Metal


Roll-Formed 4.2″ Corrugated Sheets

We are proud to be one of the few facilities in the country to roll form 4.2” (Four and Two Tenths Inch) corrugated panels. This incredibly popular style is versatile and strong, and our ability to create custom orders has allowed us to work for a number of industries in need of the specialty product. These panels feature corrugations 1 1/16 inches tall and 4.2 inches apart (From crest to crest). These dimensions make it a sturdy and attractive option for projects of all sizes.

4.2 Inch Corrugated Applications

4.2 Inch corrugated sheet metal panels have become a popular look for roofing, siding, and decorative applications. The pronounced look provides a more distinct aesthetic than smaller patterns, while the understated nature of sheet metal keeps it from being too bold.

Our purpose-built machinery can roll form the exact size of 4.2″ panels you need in a variety of gauges and substrates. If you’ve shopped around and found other shops that offer 4.2″, chances are they get their stock from us. By ordering straight from CBS, you’ll cut out the middleman, reduce lead times, and ensure your orders are going straight to the source.

Transite Panel Replacement

4.2 Corrugated panels are often used to replace transite roofing and siding. The larger pattern of 4.2 corrugated looks very similar to the old cement-asbestos panels that were used in construction projects up until the material was phased out in the 80’s due to its toxic health effects. Today, builders and developers looking to replace transite with a similarly shaped alternative find our 4.2 corrugated to be the ideal solution.
